ALCOHOL-LAMP.

Specification of Letters Patent.

Patented Jan. 28, 1908.

To all whom it may concern:

Be it known that I, ALooRN RECTOR, of the city, county, and State of NewYork, have invented a new and useful Improvement in Alcohol-Lamps, ofwhich the following is a full, clear, and exact description.

My invention relates to improvements in vapor burning lamps, andespecially in lamps intended to burn alcohol vapor.

The object of my invention is to produce a lamp of large candle powerwhich will be an equivalent for the so called arc gas lamp, which is inreality a series of burners arranged in a common globe.

My invention is intended to produce a lamp of this character which willburn alcohol vapor to great advantage, and especially to produce such alamp which has a vaporizer arranged in a way to highly gasify the fuelso that it will burn with perfect com bustion at the mantle.

My invention is also intended to produce a lamp which has its partseasily accessible, and which can be used to advantage for lighting instores and other places where much light is needed.

l/Vith these ends in view, and with the object of producing an efficientvapor burning lamp of high candle power, my invention consists ofcertain features of construction and combinations of parts which will behereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters and figures of referenceindicate corresponding parts in all the views.

Figure 1 is a vertical section of a lamp embodying my invention, andFig. 2 is a similar view of a slightly modified form of the lamp.

Referring especially to Fig. 1, the lamp has a supply pipe 10, which ispendent, and an extension 10 of the pipe is connected to the pipe 10 bya coupling 11, the latter being enarged to form a supporting head forother parts of the lamp, and the coupling carries a vaporizer tube 12,which is closed at the bottom, and which incloses the extension l0 ofthe pipe 10. Secured to the lower end of thevaporizer 12 is a cup 13, inwhich alcohol or other fuel can be placed, and ignited to start thelamp, as will presently appear. The lamp has projecting from thecoupling 11 a series of pipes l4 Which are curved downward and terminatein nozzles 1 these being reduced so as to have very small openings, andthey discharge into vertical pipes 15, which connect by couplings 16with the hangers of the mantles 17. Of course it will be understood thatthe mantles 17 can be of any approved kind, and can be hung on the tubes15 in any convenient way.

The tubes 15 are secured in the plate or diaphragm 18 which divides thehousing 19 into an upper and lower part,'and the housing can be of anyapproved design, but it is preferably divided as shown, so that airinlets 20 can be made in the upper part of the housing and the aircoming through these inlets mixes with the vapor from the tubes 14- andpasses downward through the pipes or tubes 15, mixing with the vapor andserving to promote combustion at the mantle. The mantles are inclosed ina-globe 21, which can be secured to the housing as shown at 22, byordinary set screws, or the globes can be hinged like the well known carlamp, or at tached in any convenient way. The globe can be air tight ifpreferred, or it can be pro vided with openings 23 to admit air to themantles, and the hot air can pass out through vents 24 in the housing19.

In Fig. 2 I have shown the lamp slightly modified, the vaporizing partsbeing as described, and the coupling 11 is also a little diiferent, thispart connecting with a second piece 11 having jet openings 25discharging into pipes or tubes 15 which are curved, and carrythemantles 17 as already described. In this form of lamp the top of thehousing 19 is made flat, and serves as a support for the tubes 15*, andthe upper part of the housing is dispensed with. The most essentialfeature in both types of lamp is the vaporizer comprising the parts 10and 12, and it will be noticed that the arrangement of mantles is suchthat after the initial vaporizing caused by heat from the fuel in thepart 13, the heat from the mantles will serve to heat the va orizingtube 12 very hot, and so the fuel Wi 1 be more highly gasified than inthe ordinary vapor burning lamp. The course of fuel is down through thetube 10 and up through the part 12, and so there is a good and prolongedo portunity for vaporization. Moreover, it wil be noticed that the lamphas the parts arranged so that they can be easily reached, and thearrangement is com pact and efi'icient.

It will be understood also that any number of mantles and correspondingparts connecting with the vaporizer can be used without affecting therinciple of the invention, and while in the c aims I shall refer to aplurality of these parts, it isevident that any number from one up canbe used as desired. Having thus fully described my invention, I claim asnew and desire to secure by Letters Patent let pipe extending into theclosed tube, of

the cup suspended from the lower end of the vaporizer, a series ofmantle tubes grouped around the vaporizer and carrying mantles at theirlower ends, and pipes leading from the upper end of the vaporizer anddischarging through restricted openings into the mantle tubes.

3. A lamp of the kind described, comprising. an elongated pendent vaorizer comprising an outer tube closed at its lower end, and an in-lettube extending into the outer tube, a series of mantle tubes groupedaround the vaporizer, and having mantles at their lower ends, and pipesleading from the upper part of the vaporizer and discharging through jetopenings into the mantle tubes.

4. A lamp of the kind described, comprising a vaporizer having anelongated tube closed at its lower end, and an in-let tube leading intothe closed tube, a heating cup supported from the lower part of thevaporizer, a group of mantle tubes arranged around the vaporizer andcarrying mantles at their lower ends, and discharge pipes leading fromthe upper part of the vaporizer into the mantle tubes.

5. A lamp of the kind described, comprising an elongated pendentvaporizer having a fuel inlet, a housing having a transverse diaphragmor plate dividing it into upper and lower parts, said housing fittingaround the vaporizer, mantle tubes supported in the plate or diaphragmand carrying mantles at their lower ends, an air in-let into the upperpart of the housing, means for supporting the globe on the lower part ofthe housing, heat exits in the lower part of the housing, and dischargepipes leading from the upper part of the vaporizer into the mantletubes.
